Agreed here.  I'll correct.

With regard to this, I think this isn't a problem, so I'll remove this step.

I agree here as well - so it will be "arrange data connection using an 
appropriate method (eg. PORT, PASV [RFC0959], EPRT or EPSV [RFC2428] 
command; using historical LPRT and LPSV [RFC1639] for this purpose is 
strongly discouraged);"

With this respect NLST was borrowed from RFC 1738.  So I'll change so 
that (4a) and (4b) will not mention NLST but rather "an appropriate 
method, like LIST, NLST [RFC0959] or MLST [RFC3659] command"

Thanks for your feedback.
